Prevalence and levels of autoantibodies in cerebrospinal fluid from patients with NPSLE and controls.

NPSLE = neuropsychiatric systemic lupus erythematosus; SLE-surgical = lupus patients who underwent elective surgery; SLE-septic meningitis = lupus patients with septic meningitis, Non-autoimmune = patients without autoimmune diseases.1P2P3P4P = 0.006 versus SLE-septic meningitis5P6P7The NMDAR antibody was measure in 34 SLE-CNS patients, 5 SLE-PNS, 12 SLE-surgical, 5 SLE-septic meningitis, and 25 Non-autoimmune patients.8Autoantibodies levels represent the mean (±SD) among the patients in whom they were positive. The number of patients in each group for a particular antibody corresponds to the prevalences displayed in the upper panel.
